To all col/m t may concern:

` Be it known that I, Maurin JELALIAN, a

y citizen. of theUnited States, residing at the city of Cranston, inthe county of Providence and State ofRhode Island, have invented certain new and useful Improvements in Spring-Cushion lDevices for Vehicle-Tires,fof which the following is a specification.

' wearing out.

This invention is; an attachable spring cushion device for vehicle tires Consisting of two opposite base members adapted to be secured to the tire and provided with cushioning arrangement toserve as a spring cushionfor the latter and to prevent the same from The improvements are fully` described in the following specification, illustrated by the accompanying sheet of drawings, in which like reference characters designate like parts. In the drawings:

Figure l is a side elevation of a vehicle wheel provided with a tire, illustrating the improved cushioning device as mounted thereon, and one of the opposite base members shown in section.

Fig. 2, an enlarged, transverse, sectional view, of Fig. 1. Fig. 3, an enlarged, fragmentary plan view of the device; Fig. 4.-, is a side elevational view, illustrating a modified form` of the device; Fig. 5, is an enlarged, transverse, sectional view of Fig. Il; Fig.- 6, is another modified form of arrangement of parts `of the device.

Referring to the drawings, av-- desig- Vnates a vehicle-wheel provided with the tire -e to which the improved cushioning device is adapted to be applied.

Mounted upon the tire ?J are opposite base members 6, provided with projecting portions and bolted to one another as at a2, a2 i Each base member 6, e comprisestwo pivotally united slidable base support members lt-3, 3 adapted to be secured to the tire Z2- and having like sets of integral shafts m n projecting from the outer faces thereof, and slidable guard rail mem-y bers P, Zfwhich are provided with tubular members Q, Q and slidably mount ed upon the end portions of the shafts f/L, n of the base support members 763, 7c'` Coilspring Z, 2fsurround said shafts and having one of their ends secured to the slidable base support members 753, c3

and the other ends attachedcto the end portions of the tubular members Q, Q of the slidable guard rail members Z9, Q as shown by Fig. l.

rihe device is attached to the wheel by bolting the complementary sections of the base members 6, together at (12, c2- and -strapping them to the fellyjof the wheel. 'i

For this lat-ter purpose straps 63, e3- are arranged, which are fastened at their to the base members 6, by hooks The base members of the complementary sections are also provided `with outwardly projecting hooks 76, t0 receive straps i, r extending from hooks Z2 Z* which project downwardly from the bottom faces of the slidable guard rail members P, Z9 of the base members e, Q as shown by Fig. 2. Secured upon the top face of each of said base members 6, e is a strip of layer af/4, a4

When the slidable guard rail members Z9, Z9 of the base support members eare worn down they may be removed and replaced, by new ones in place thereof to provide new' ftread elements.

In Fig. 4, is shown a modified form of the device wherein the tread elements extend longitudinally of the tire. For this purpose a plurality of wire supporting base members c, are provided which are secured to the tire by straps 63, e3 fastened at their ends to the felly of the wheel.

`'.lhe wire supporting base members c, sare provided with slidable shafts Q, Q and also coil spring connections Z, Z and strips of layers M and strapping arrangement in the same manner as shown by Fig. 2.

Also provided upon said base-members c are hooks r r4 through which extend flexible wires Q', Q which serve as a tread element. f

rllhe tread-wires as shown extend longitudinally of the tire and are spaced around its peripheral tread portion.

ln Fig, 6 is shown another modified form of the device and wherein the iexible wires .Q, Q which serve as a tread element, are arranged in the same manner as shown by Fig. 4, and secured in place by transversely extending wires u, uhaving their ends secured to the strips 64, e4 which are placed against the sides of the tire -25-' and extending around the outer circumference thereof and having 'straps -Z2,

2for attachment.

What I claim as new and desire to secure by Letters Patent is:

l. In an attachable spring-cushion tread device for vehicle -tires, the combination with twov base members adapted to be bolted together to yextend longitudinally ofthe tire and encircle the same, each of said base members comprised of a pair of pivotally united sections having slidable shaft support members provided with slidable shaft projecting Jfrom the outer faces thereof, and also slidable guard rail members provided with tubes and slidably mountedvupon the end portionsof said slidable support members, coil springs encircling said shafts and having one of their ends secured upon the top face of said slidable shaft support members and the vother ends attached to the end portions of the tubular members of said Y slidable guard railV membersyhooks project- Y ing inwardly from the latter;Y and having strap connections extending from said hooks to saidsldable shaft support members, and also strap connections from the latter for attachment to the felly of the wheel of the vehicle.

2. In an attachable spring-cushion tread ydevice for vehicle tires, comprised of two base members of pivotally united sections having slidable shaft support members provided with slidable shafts arranged in pairs projecting from the outer faces thereof and also slidable guard rail members provided with tubes and slidably mounted upon the end portions of said slidable shaft support members, coil spring connections between said slidable guard rail members and said slidable shaft support members of said base members a strip of layer extending upon the top face of each pair of said slid-able gua-rd rail members of said base members and strap connections from the latter to the hooks projecting outwardly from said slid able shaft support members.

In testimony whereof I alix my signature in presence of two witnesses.
